What is the role of authority in the function of getting things done?
I bought a book about this 10 years ago, so these aren't new challenges. I can't remember a single thing from the book. When I looked at it on Amazon, it was more about project management and Agile. I am talking about decision-making and the mindsets within an organization. But I know why a PM would write a book about this, so maybe I should reread it.
There is thinking (in tech at least) that titles shouldn't matter. If you can make a case for what you are trying to get done, you should be able to accomplish what you need. Anyone who has tried this knows that results are less predictable.
Other factors in the equation include the other party's willingness to change and the time needed to build a cohesive case. The easy answer is, "Just be really persuasive" (A.B.P.).
But crafting a long, persuasive argument isn't always feasible. And it doesn't win against someone who has an investment in the status quo.
The answer is something like: you have to cultivate your persuasiveness. Then you make your best effort; if you lack the authority, be prepared to let it go when things don't go your way. This is hard to do.
If you have the authority, you can tell people to do it your way. Sometimes, that's how it has to work, and you take the lumps when you are wrong. This is especially true if you are incompetent. Eventually, incompetence will catch up with you, no matter how persuasive you are.
The challenge of authority is that when you make people do something, regardless of the result, some resent you or half-ass it. Those people are hard to work with, especially when you are competent. When you are incompetent, the whole lot of you are probably hard to work with.
